The Wolf at the Door: Edward Walton Serial Killer Between 1904 and 1908, Edward Walton killed at least four people-possibly five-across multiple states, exploiting the jurisdictional fragmentation and primitive communication systems of Progressive Era America to evade capture for years. A transient laborer moving through the circuits of mining camps, industrial towns, and railroad communities, Walton murdered his estranged wife in Chicago, shot a man in Pennsylvania, beat his girlfriend to death in Ohio, and killed a young woman in rural West Virginia who refused his sexual advances. Each time he killed, he immediately fled to a new jurisdiction, establishing a fresh identity under a new alias, rendering investigation impossible in an era before centralized criminal databases, fingerprint systems, or effective interstate cooperation. Walton's capture came not through detective work but through circumstance: a 400-person posse trapped him after his final murder in Gypsy, West Virginia, preventing the flight that had protected him previously. His subsequent confession revealed a pattern of violence against women who asserted autonomy, illuminating both the gendered nature of serial violence and the systemic law enforcement failures that enabled transient killers to operate with near-impunity in an age of mobility without surveillance.
